莱州湾南岸滨海湿地景观破碎化分析

Analysis on Landscape Fragmentation of Coastal Wetlands Along South Coast of the Laizhou Bay

以莱州湾南岸滨海湿地为例,利用遥感和GIS技术对滨海湿地景观特征及景观破碎化程度进行了分析。结果表明,莱州湾南岸滨海湿地景观破碎化严重,整体斑块密度为6.7个/km2,廊道密度为0.01 km/hm2,人工景观破碎化程度比自然景观高,人类活动是造成莱州湾南岸滨海湿地景观破碎化的主要原因。最后本文从景观生态学角度对莱州湾南岸滨海湿地退化进行了定量评价。

In this paper, the landscape characteristics and landscape fragmentation of coastal wetlands along south coast of the Laizhou Bay are analyzed using remote sensing and GIS techniques. It is shown from the analysis results that the coastal wetlands in the area have undergone severe fragmentation with a patch density of 6.7 ind. /km^2 and a corridor density of 0.01 km/hm^2 , the fragmentation degree of artificial landscape is higher than that of natural landscape, and the human activities are the main cause for the landscape fragmentation of coastal wetlands in the area. Finally, the quantitative evaluation of degradation level of coastal wetlands along south coast of the Laizhou Bay is made.
